A semi-truck driver struck a barricade Wednesday afternoon on Highway 1, north of the Goldstream Provincial Park turnoff at Finlayson Arm Road.
No other vehicles appear to be involved in the crash.
Drive BC says the incident happened one kilometre north of Finlayson Arm Road. There was a southbound lane closure but the road has since reopened.
On Thursday afternoon, West Shore RCMP said the 3:17 p.m. on Wednesday, a semi-truck slid into a barricade and then crashed into the rock face near the 3400-block of the Trans-Canada Hwy. The highway was blocked for a period of time as crews worked to clear the truck.
The B.C. government had said earlier Wednesday that travel was not recommended on Highway 1 from south Nanaimo to Victoria, as well as Highways 14, 17 and 18.
Persistent snow, high winds and cold temperatures are causing poor road conditions, the government says. Those who must travel are asked to use extreme caution and drive to the conditions. The ministry advises travellers to expect winter conditions for the rest of the week.
All motorists are encouraged to plan ahead and drive according to weather and road conditions, slowing down when they encounter bad weather or limited visibility.
